For example, suppose the first BWP includes 51 frequency domain units (ie, N = 51), and the 51 frequency domain units correspond to 6 comb teeth (ie, M = 6), and the first offset value is {2, 5} Frequency domain units, then the frequency domain unit Y included in the first comb tooth satisfies:

Mod (Y, 6) = {2, 5},

Optionally, in the embodiment of the present application, the terminal device determines a frequency domain unit included in the first comb tooth according to a first offset value and the first indication information.

For example, the first offset value includes an offset value set, and the terminal device determines one or more offset values in the offset value set according to the first indication information, and determines the first value according to the one or more offset values. Comb consists of frequency domain units.

Optionally, the number of offset values included in the first offset value is less than or equal to the M value.

By way of example and not limitation, it is assumed that when the first SCS is 30 kHz, the first BWP includes 51 PRBs, the first BWP includes 4 comb teeth, the offset value set includes {0,1,2,3}, and the first indication information Used to determine the use of {2,3} in the offset value set, then the index of the PRB included in the first comb tooth satisfies Mod (Y, 4) = {2,3}, where the range of Y values is 0 To 50, that is, the index of the PRB included in the first comb is {2, 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 3, 7, 11, 15, 19, 23, 27, 31, 35, 39, 43, 47}.

Therefore, through the above resource allocation mode, resource allocation in units of comb teeth under different SCS can be achieved.

Optionally, in the embodiment of the present application, the terminal device determines that there is at least one frequency domain unit in the first BWP that cannot be divided by the first comb teeth, and the at least one frequency domain unit is located in the first BWP.

Optionally, the first BWP cannot be divided by the first comb teeth, which can be understood as that the frequency domain units included in the first BWP cannot be divided by the comb teeth, or the frequency domain included in each comb tooth When the number of units is the same, the first BWP includes not only an integer number of comb teeth, but also a frequency domain unit that does not belong to any comb teeth. For example, suppose the first BWP includes 106 PRBs and the first BWP includes 10 comb teeth, where each comb tooth includes 10 PRBs. That is, in addition to 100 PRBs corresponding to 10 comb teeth, the first BWP also includes 6 PRBs that cannot be divided by the comb teeth. The six PRBs are located in a first reserved position in the first BWP.

Optionally, the first reserved position includes a center position of the first BWP.
